My Posts Not Visible In Google+ Community

I think @AI Everett is 100% correct. The only suggestion I would make in addition to his is this:

• Copy your existing profile picture (if you really like it and want to keep it, else upload a new profile picture; it is your choice). Leave this image in the album called "Scrapbook photos".

• Move your existing profile picture, which will include your friends' comments (I'm guessing you want to keep them), from Scrapbook photos to a different album. You can use an existing, private album, or create a new album that is accessible only to certain people or circles.

• Use the new version of the picture in your Scrapbook photos as your profile picture. Make sure to disable comments on in it!

In Google+ you only see posts in your Stream from people you follow yourself. But of course, that person can decide itself whether or not it shows up in your Stream.

Sharing to Circles and Extended Circles (in the circles of someone in your circles) just gives the people in your circles and those in their circles the right to see your post in their Stream if they are following you.

So if you have people in your circles that don't have you in theirs, they won't see your posts shared with them in their Streams. Only if f.e. I am following you and you appear to be following someone that follows me, I will see your Extended Circles post while I'm not in your circles.

I hope this gives a good explanation. It would be wrong to be able to push posts in someone's Stream without having them chose for it, right?

Btw, also, when f.e. someone would be in your Extended Circles but is not following you, he will also be able to see the post when he gets a link to it. So, when you get a link to a post, you will be able to see it when you fall under the audience of the post (either a circle, all the poster's circles/Extended Circles or Public).
